MAKE SURE YOUR POWER SUPPLY IS OFF AND UNPLUGGED BEFORE WIRING
Locate the PK-232 Power Cable in the accessory bag. Strip off
just enough insulation from the ends to connect it to your 12-14
Volt DC regulated power supply.
The Center pin of the coaxial power plug is POSITIVE. Connect
the lead with the White stripe to the POSITIVE (+) lead on your
power supply. Check this with an Ohm-meter if you have one.
Connect the solid Black (GROUND) lead to the NEGATIVE (-) lead of
your power supply. (The AEA AC-4 Wall Transformer is already
wired correctly.)
Connect the Coaxial power plug to the 13 VDC Power Receptacle on
the left rear of the PK-232. DO NOT CONNECT YOUR COMPUTER YET.
Plug in your power supply or AC-4 and turn on power. Turn on the
PK-232 by depressing the Power Switch on the front of the unit.
WATCH CLOSELY FOR THE FOLLOWING:
At power-on the four LEDs on the left of the PK-232 should light
for 1 second and the BAUDOT LED should then light and remain lit.
If this occurs, then switch OFF the PK-232 and move on to section
2.3.
If no LEDs light then re-check the above steps to insure that 12-14
VDC is available at the power plug and the center pin is POSITIVE.
If any LEDs other than the BAUDOT LED light then the PK-232 has
probably been initialized. If the PK-232 has been initialized it is
ready to communicate with a computer or terminal at a specific baud
rate (probably 300, 1200, 2400, 4800 or 9600 bits/sec). If you know
what this baud rate is then you should continue with the installation
at section 2.3 keeping this in mind.
If you do not know what baud rate the PK-232 has been initialized to
then you should remove the Lithium battery jumper JP1 from the Berg
posts which will reset the PK-232. To do this, do the following:

o
Disconnect power and all cables from the PK-232 and turn the unit
upside down.
locate the hole immediately behind the RADIO-1/RADIO-2 switch.
With needle-nose pliers or a tweezers gently lift the shorting
jumper up off the Berg Posts.
Wait approximately 2 minutes to insure that the memory has
"forgotten" the old parameters.
Carefully replace the jumper over the posts.
If the above did not restore proper operation of the PK-232 frontpanel
LEDs, then contact Timewave Technical Support Department as
described in the front of this manual.
